Antenova has introduced two new chip antennas designed specifically for use in 3G and 4G diversity applications with very small PCBs.
The Integra and Inversa are ultra-compact (just 3.3 mm high) and can be used in slim-line devices that will be unobtrusive in use.
The antennas perform efficiently with a small ground plane, and can even be used on PCBs as small as 65 mm. Where the PCB is smaller than 75 mm, Antenova provides an additional active tuning circuit to overcome bandwidth reductions.
These antennas are designed to work singly or in pairs for MIMO and diversity systems. They have beam steering which gives good isolation and cross-correlation and will provide faster downloads in diversity applications.
One or two antennas can be used on a PCB. They are made in left and right versions i.e they are different part numbers based on whether they are going to be placed on the left side of the PCB or the right side. This gives designers plenty of combinations and options for placing them in a design while leaving space for other components on the board. The ‘keep-out’ area around the antennas is minimal, allowing them to be placed close to other components.
The Integra antenna, part numbers are SR4L049-L / SR4L049-R, and the Inversa antenna part numbers are SR4L034-L / SR4L034-R.
Integra and Inversa operate at different frequencies. Integra covers 791-960 MHz, 1710-2170 MHz, 2300-2400 MHz and 2500-2600 MHz, for European markets, while Inversa covers 698-798 MHz, 824-960 MHz, 1710-2170 MHz, 2300-2400 MHz and 2500-2690 MHz and is built for global markets.
These antennas are suitable for small tracking devices, OBDs, 4G Mi-Fi routers, medical equipment, tablets, MIMO systems, Femtocell and Pico stations and remote monitoring. They were initially announced at CES and the Embedded World exhibition.
At the Embedded World exhibition, Antenova's Robusta antenna won the show’s Embedded Hardware award. The Robusta antenna is optimized for use on metal surfaces.
